Reduce variation in rootDepth between different threads 8d858783e1bcf4266f30614c0f69677835976a22
The binaries are 'Windows', done on GCC520 posix seh make profile-build ARCH=x86-64-bmi2 COMP=mingw and make profile-build ARCH=x86-64-bmi2
[A] Static (no lto no libs required)
https://www.dropbox.com/s/aja7lrpa08evoom/stockfish_301015_x64_bmi2.exe?dl=0[B] LTO (no static libs must be with binary)
https://www.dropbox.com/s/n2767f7di2dz6vl/Sf%20flto%20dll%20must%20be%20with%20exe.zip?dl=0Both are also attached here.
This is how these bench against abrok builds
[A] Base = abrok Test = Static (no lto)
Results for 10 tests for each version:
Base Test Diff
Mean 2889703 3021925 -132222
StDev 4520 6155 7911
p-value: 1
speedup: 0.046 (4.6%)
[B] Base = abraok Test = lto (no static)
Results for 10 tests for each version:
Base Test Diff

This is a great result!
For the superfinal we have to provide to Martin some optimized binary (few days in advance), otherwise he will fallback on the abrok ones.
So I would ask interested people to please provide a binary faster than the abrok defaults.
I guess we can use current master version, there is some work on lazy formula for 24 cores, but I am not sure it will end up in time (few days before final, so within tomorrow, more or less).
